check out places like odesk or elance and bid your project out. Cut out as many features(bells and whistles as you can). Get a credit card for 5k-10k let someone else do the work and pay with a credit card. Now take your salary every month subtract the monthly credt card payment. Divide that number in half and send it to me for saving you a ton of risk a lost revenue. Seriously though at least bid out your project and see what it will cost and compare that to how much you'll make over the next year.
